Hi,
If you are serious about winning in a lottery you must use wheels. Without them, even if you have the best numbers, you will be wasting your money away.
Wheels allow you to TARGET certain level of wins and GUARANTEE that you will get the target wins if you hit (match) X numbers out of Y numbers selected - no matter what numbers you match all combinations are covered. This alone significantly increases your chances of winning.
Generally, there are 2 types of wheels - full and abbreviated. Full wheels GUARANTEE that you get your target win if you match X numbers out of Y numbers in the wheel. Abbreviated wheels do not provide this guarantee and for that very reason I don't use them.
It is important to realize that wheels are not equal. They may have different number distribition paterns that may affect their winning efficiency. While they always guarantee the minimum win some may not deliver more than that, even if you match all numbers in the wheel. Obviously such wheels should be avoided and replaced by the more efficient ones.
Wheels with similar parameters (wins guaranteed, numbers of tickest) may have significantly different levels of efficiency - by which I mean how often they win. There are wheels that win frequently and wheels that win only sporadically. Moreover, the performance of the same wheel may fluctuate over the period of time.
You should also COMPARE the performance of several wheels in THE SAME TIME FRAME. This will allow you to see which are more reliable and more CONSISTENT. If the performance is similar for several wheels pick the one that uses the smallest number of tickets.
How do you check the performance of a wheel in the recent past? The only way to do that is backtracking. Go back several draws back (I usually go back 50 draws) and check how your selections and wheels scored draw after draw.
Once you have the lists of the most recent scores for the wheels you like, in the same time frame, you may start comparing them. You may compare how many wins each wheel generated, or compute the monetary gains each wheel generated and match them against the cost of tickets - the better the ratio the better the wheel.
The same wheel may perform differently at different times. It may win consistently for a while and then go blank. Such fluctuations are the NORM, not exception. Therefore, when you notice that your favourite wheel performance is fading away switch to another one that has better prospects for the near future. Always keep a watch on more than one wheel so you have an alternative ready when a need arises.
I hope that this will help you to undertand what wheels are and how they can help you in winning the "cash" as you indicated in your question.
